Our paper on turtle origins is finally out in Current Biology, with two major implications for our understanding of reptile evolution 🐢 #Paleontology #Turtles #Evolution www.cell.com/current-biol...

Happy #FossilFriday here is Guidraco venator, a genus of Pterosaur from the early Cretaceous of China. Also One of a few Pterosaur genera that made its appearance the Netflix documentary #thedinosaurs

Happy #FossilFriday here is Attenborosaurus a genus of Pliosaurid Plesiosaur from the early Jurassic of England. Named after the legendary Sir David Attenborough who turns 100 today

New paper! We conducted a preliminary histological survey of the vertebrates from the Late Triassic Pebbly Arkose Formation of Zimbabwe. This assemblage (230 Ma) contains the oldest-known definitive dinosaurs from Africa! doi.org/10.1111/joa....

Happy #FossilFriday from the Royal Tyrrell Museum! Today is also the first day of CSVP, looking forward to a great conference! #paleontology #CSVP2026 #SVP

Happy #FossilFriday! Here is Hyperodapedon a genus of Rhynchosaur from the late Triassic of Europe and Asia. Art by Gabriel Ugueto

Institute of Paleobiology of the Polish Academy of Sciences & the University of Warsaw invite participats for paleontological excavations, in July-August. Accommodation and meals are provided. The digs uncover Triassic vertebrates in Polish Silesia. Details in thread 🧵

Happy #FossilFriday meet Kaprosuchus saharicus! Nicknamed the “Boar croc” Kaprosuchus lived during the late Cretaceous of Niger 🇳🇪 roughly 95 million years ago. Kaprosuchus is a member of the Mahajangasuchidae an early branch of notosuchian crocodiles

Happy #FossilFriday here is Diplocaulus a genus of lepospondyl amphibian from the Late Carboniferous and early Permian period. A distinctive feature of Diplocaulus are its long horns at the back of the skull that are formed by elongation of the squamosal and tabulars

Happy #FossilFriday here is Coelophysis! A genus of Triassic dinosaur that lived in what is now New Mexico. Coelophysis is one of the best sampled dinosaur genera with dozens of individuals discovered from the Ghost Ranch locality in New Mexico.

Very sad news in Paleo, Hans Dieter-Sues passed away today. Hans was a phenomenal Paleontologist and wonderful person who will be dearly missed

Terrible news that Hans-Dieter Sues has died. Way too young. Hans (on the right) & Sasha Averianov (left) invited me to study Timurlengia with them. I'll always appreciate it. Hans was eminent, always nice and cheerful to me, a man of ethics and faith. RIP.

Happy #FossilFriday here is Microraptor a genus a Dromaeosaur from the early Cretaceous of China. A unique feature of Microraptor is the presence of flight feathers on the legs in addition to the arms.

Astronomers are planning ambitious telescopes to search for signs of life on distant planets. A newly discovered world might just be the perfect target. Learn more: https://scim.ag/3Z75OMi

Happy #FossilFriday here is Mesosaurus tenuidens a genus of Aquatic para reptile from the early Permian of South Africa and South America. Mesosaurus fossils were instrument in proving continental drift as remains were found in two widely separated regions

Happy #FossilFriday here is Beelzebufo ampinga an extinct genus of Hyloid frog from the late Cretaceous of Madagascar. Beelzebufo was the largest frog to ever live with an estimated size of 42 cm and likely preyed on juvenile dinosaurs.

A shake-up of the dinosaur family tree! Rhabdodontids are not ornithopods. They are ceratopsians. There were horned dinosaurs in Europe! As shown by a new fossil of Ajkaceratops from Hungary! Check out our new study, led by @tweetisaurus.bsky.social ⤵️

A #PrehistoricPlanet Christmas, borrowed from jurassic_world_clipz on TikTok :) Merry Christmas everyone!

I want to wish everyone Merry Christmas and Happy Holidays with this quick sketch of two Microraptorine dinosaurs in the snow ❄️. I hope everybody is having a great day and enjoying the presents! 🎁 🎄 🎅 Merry Christmas and Happy Holidays!

Second #FossilFriday post, I also got to see the very cool Polycotylid Plesiosaur that is on display at the Natural History Museum of Los Angeles county that has a fetus preserved (see the second photo for a closer look

Happy #FossilFriday this week I got to visit the Natural History Museum of Los Angeles County to look at the Maastrichtian Struthiomimus that is on display. I also got to see the rest of the dinosaur gallery which is spectacular!

#FossilFriday The awesome new article in Science by @griffinlabpaleo.bsky.social et al. adds more evidence for the validity of Nanotyrannus by showing that the hyoid bone in the holotype has adult bone histology. Here are some more images showing the ceratobranchial bone in place in the skull. 🦖

Happy #fossilfriday here is Dinornis a genus of Giant Moa that lived in New Zeland until as recently as the 1500s. Dinornis itself was the tallest bird to ever live with females standing 10 feet tall, a phenomenon known as reverse sexual dimorphism. #PrehistoricPlanetIceAge

#FossilFriday here is a Triceratops skeleton on display at the Royal Tyrrell Museum

Another SVP meeting in the books. It was a success and a great time #2025svp

Thanks to everyone who turned up bright and early for my #2025SVP talk. Glad to see some love for the gomphs!

Thank you to everyone who visited my poster yesterday. Looking forward to a great rest of the conference! :) #2025SVP

Happy #FossilFriday Here is Temnodontosaurus trigonodon a genus of Ichthyosaur from the Early Jurassic of Europe. A notable feature of Temnodontosaurus was its incredibly large eyes the largest of any known vertebrate.

Here you go. Note: it is still the unformatted version! Zanno, L.E., Napoli, J.G. Nanotyrannus and Tyrannosaurus coexisted at the close of the Cretaceous. Nature (2025). doi.org/10.1038/s415...

For those who are attending SVP this year. Feel free to stop by my poster #SVP2025
